Only option to store openhour and closehour as string. Making arithmetic operation on these columns complex.
Hive do not have time datatype. Is there an option to create a custom datatype to handle this
select cast('0130' as time) from test_table; Error: Error while compiling statement: FAILED: ParseException line 1:22 cannot recognize input near 'time' ')' 'from' in primitive type specification (state=42000,code=40000)
Hive supports time in form of timestamp, hence, the error as "time" is not recognized. If you are to hold the 0930 alone as openhour, then apt datatype would be string.
In case, you could hold data like "2018-10-15 09:30:00" as openhour, then you could use timestamp as datatype and select query would be like "select cast("2018-10-15 09:30:00" as timestamp) from test_table.
